Hastelloy C276 Bright Bar / Hot Rolled Bars Diameter 6 - 300mm Polishing C276 Shaft for Oil
Hastelloy C276 bright bars, including hot-rolled variants with a diameter range of 6 - 300mm and polished C276 shafts, are high-performance nickel-based superalloy products tailored for demanding oil industry applications. Their unique composition and processing make them a reliable choice for environments where corrosion resistance, high-temperature stability, and mechanical strength are critical.
1. Product Parameters
The key technical parameters of Hastelloy C276 bright bars/hot-rolled bars and polished shafts define their dimensional accuracy and material integrity, ensuring compatibility with oil industry equipment:
| Parameter Category | Specific Details |
| Diameter Range | 6mm - 300mm (covers small-diameter precision parts and large-diameter load-bearing shafts) |
| Bar Length | Standard: 1m - 6m; Customizable: Up to 12m (based on customer equipment assembly needs) |
| Surface Finish (Bright Bar) | Polished finish: Ra ≤ 0.8μm; Mirror finish (optional): Ra ≤ 0.2μm (reduces fluid friction and corrosion accumulation) |
| Surface Finish (Hot-Rolled Bar) | Black oxide finish (as-rolled) or pickled finish (removes scale, improves surface cleanliness) |
| Tolerance Grade | Diameter tolerance: h9 - h11 (for bright bars); h12 - h14 (for hot-rolled bars) (complies with precision machining requirements) |
| Straightness | ≤ 1mm/m (ensures stability during shaft installation and rotation) |
| Chemical Composition | Nickel (Ni): ≥ 57%; Chromium (Cr): 14.5% - 16.5%; Molybdenum (Mo): 15% - 17%; Tungsten (W): 3% - 4.5%; Iron (Fe): 4% - 7%; Carbon (C): ≤ 0.01%; Silicon (Si): ≤ 0.08%; Manganese (Mn): ≤ 1% |
2. Core Performance Characteristics
Hastelloy C276 bright bars excel in harsh oilfield and refinery environments due to their outstanding comprehensive performance, addressing the industry’s biggest pain points (e.g., corrosion from sour oil/gas, high-temperature fluid erosion):
- Exceptional Corrosion Resistance: Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in aggressive media common in oil operations, including sour crude (containing H₂S), chloride-rich brines, and acidic refining fluids (e.g., sulfuric acid, hydrochloric acid). It is also immune to intergranular corrosion after welding or heat treatment.
- High-Temperature Stability: Maintains mechanical strength and corrosion resistance at temperatures up to 1093°C (2000°F), making it suitable for high-temperature oil refining processes (e.g., catalytic cracking, hydrocracking) and downhole applications in deep, high-temperature wells.
- Superior Mechanical Strength: Tensile strength ≥ 795 MPa; Yield strength (0.2% offset) ≥ 379 MPa; Elongation ≥ 40%. Even after long-term exposure to high temperatures or corrosive environments, it retains minimal strength degradation.
- Excellent Machinability & Weldability: The bright bar’s polished surface reduces tool wear during machining, while the alloy’s low carbon content (≤ 0.01%) ensures weldability without post-weld heat treatment—critical for on-site assembly of oilfield equipment.
3. Industry Standards
Hastelloy C276 bright bars, hot-rolled bars, and polished shafts adhere to global industry standards to ensure consistency, quality, and compatibility with international oil projects:
| Standard Type | Relevant Standards |
| ASTM (USA) | ASTM B574 (Nickel Alloy Rods, Bars, and Wire); ASTM B622 (Nickel Alloy Plate, Sheet, and Strip—reference for base material quality) |
| ASME (USA) | ASME SB574 (for pressure vessel and boiler applications in oil refineries) |
| DIN (Germany) | DIN 17750 (Nickel and Nickel Alloy Bars and Rods) |
| EN (European Union) | EN 10088-3 (Stainless Steels—Part 3: Semi-Finished Products, Bars, Rods, and Wire of Corrosion-Resistant Steels for General Applications—extended to nickel alloys) |
| JIS (Japan) | JIS H4552 (Nickel Alloy Bars) |
4. Similar Grades
While Hastelloy C276 is a benchmark for corrosion resistance in the oil industry, several 相近牌号 (similar grades) offer comparable performance for specific scenarios. The table below helps distinguish their applicability:
| Grade Name | Country/Region of Origin | Key Difference from Hastelloy C276 | Application Scope in Oil Industry |
| Hastelloy C22 | USA (Haynes International) | Higher chromium (20% - 22%) and lower molybdenum (12.5% - 14.5%)—better resistance to oxidizing acids (e.g., nitric acid) | Oil refining units handling oxidizing media (e.g., nitric acid-based desulfurization) |
| Inconel 625 | USA (Special Metals) | Contains niobium (Nb: 3.15% - 4.15%) instead of tungsten—superior high-temperature creep strength | High-temperature downhole tools and furnace components in oil refineries |
| Monel 400 | USA (Special Metals) | Nickel-copper alloy (Ni: 63% - 70%, Cu: 28% - 34%)—excellent resistance to seawater but poor in sour crude | Offshore oil platforms (seawater contact parts) but not suitable for sour oil/gas wells |
| Alloy 59 | Germany (VDM Metals) | Higher nickel (≥ 58%) and molybdenum (15% - 16.5%)—enhanced resistance to strong reducing acids | Extreme sour oil wells (high H₂S and chloride concentrations) |
5. Application Fields in the Oil Industry
Hastelloy C276 bright bars and polished shafts are widely used across upstream (exploration/production), midstream (transportation), and downstream (refining) oil operations, where durability in harsh conditions is non-negotiable:
-
Upstream (Oilfield Exploration & Production):
- Downhole shafts and mandrels for electric submersible pumps (ESPs) in high-temperature, high-salinity wells.
- Valve stems and choke shafts for wellheads (resisting corrosion from sour gas and brines).
- Drill collars and tool joints for deep, corrosive wells.
-
Midstream (Oil & Gas Transportation):
- Compressor shafts and pump shafts for pipelines transporting sour crude or natural gas.
- Valve components in pipeline terminals (resisting chloride-induced corrosion from coastal environments).
-
Downstream (Oil Refining & Petrochemicals):
- Shafts for centrifuges and mixers in catalytic cracking and hydrotreating units.
- Heat exchanger tubesheets and reactor internals (withstanding high temperatures and acidic process fluids).
- Pump shafts and agitator shafts in sulfur recovery units (resisting corrosion from sulfuric acid byproducts).
6. Packaging Methods
